Abstract

L'invention concerne un dispositif d'aspiration ainsi qu'un dispositif de buse présentant une structure simple et dans lesquels, lorsqu'un travail d'aspiration est exécuté avec une buse proche d'un objet ou en contact avec un objet, un fluide est projeté automatiquement depuis une buse vers l'objet et le fluide ayant touché l'objet peut être absorbé. De plus, lorsque la buse est écartée de l'objet, le jet du fluide vers l'extérieur de la buse est stoppé automatiquement. Dans un dispositif d'aspiration (1), une buse (12) de fluide destinée à envoyer un jet de liquide vers une extrémité d'ouverture de buse est ménagée dans une buse (11). Lorsqu'une ouverture (13) de la buse (11) est ouverte, l'air extérieur (300) aspiré par l'ouverture (13) jusque dans la buse (11) l'emporte sur le fluide projeté en jet par la buse (12) à fluide, permettant l'aspiration du fluide avec l'air extérieur (300) sans que le fluide ne soit projeté en jet par l'ouverture (13). Lorsqu'une quantité d'air extérieur aspirée dans la buse (11) est réduite par rapprochement de l'ouverture (13) de l'objet ou par contact avec celui-ci, un fluide projeté en jet par la buse (12) à fluide l'emporte sur l'air extérieur et est projeté en jet vers l'objet, ce qui rend possible l'aspiration du fluide ayant touché l'objet.
